11.5.10.2 Measuring the trip limit of set values
M14922-6 v8
1. Check that the input logical signals BLOCK and ENABLE and the output logical signal TRIP are all
logical zero.
2. Activate the input ENABLE on the STBPTOC (50STB) function block
3. For a short while inject a current (fault current) in one phase to about 110% of the set operating
current, and switch the current off.
Observe to not exceed the maximum permitted overloading of the current circuits in the IED.
4. Switch the fault current on and measure the operating time of STBPTOC (50STB).
Use the TRIP signal from the configured binary output to stop the timer. The operation should be
instantaneously.
5. Activate the input BLOCK on the STBPTOC (50STB) function block.
6. Switch on the fault current (110% of the setting).
No TRIP signal should appear.
7. Switch off the fault current.
8. For a short while inject a current (fault current) in same phase to about 90% of the set operating
current, and switch the current off.
9. Switch the fault current on.
No TRIP signal should appear.
10. Switch off the fault current.
11. Reset the ENABLE binary input.
12. Switch the fault current on.
No TRIP signal should appear.
13. Disable the fault current.
11.5.10.3 Completing the test
M14922-50 v4
Continue to test another function or end the test by changing the TESTMODE setting to Disabled.
Restore connections and settings to the original values, if changed for testing purposes.
